The modern rhythm of life dictates its own conditions, and the need to constantly hold a smartphone in your hands becomes not only inconvenient, but also often dangerous. Wireless headphones have turned from an accessory for music lovers into an indispensable communication tool for millions of users around the world. The ability to free your hands while talking, while driving, while working out or just doing household chores provides a level of comfort that you quickly get used to.
However, despite the ubiquity of Bluetooth technology, many owners of smartphones based on the operating system Android have questions when first getting acquainted with headset. The process of pairing, customizing control buttons, and optimizing sound quality may vary depending on the device model and operating system version. In this article, we will analyze in detail all the stages, from basic connection to solving specific sound problems.
You will learn not only how to receive calls, but also control the volume, switch between speakers and use voice assistants for maximum convenience. Proper setup will allow you to forget about wires and enjoy crystal clear sound in any situation. Let's move from theory to practice and set up your device for perfect communication.
Basic preparation and process of pairing devices
The first and most important step is the correct connection of the smartphone and headset. Most modern models, such as Samsung Galaxy Buds, Xiaomi Redmi Buds or Realme Buds, switch to search mode immediately after being removed from the case when turned on for the first time. If you are using the device repeatedly, you may need to force it into visibility mode by holding down the touchpad or physical button on the case for a few seconds until the indicator starts flashing blue or white-blue.
On the smartphone side, you need to activate the wireless module. To do this, lower the notification shade and find the Bluetooth icon, or go to system settings via path Settings → Connected devices → Connecting a new device. The Android system will automatically scan the broadcast and offer a list of available gadgets. Find the name of your headset in the list and tap it to initiate the pairing process.
⚠️ Attention: If your smartphone sees the device but refuses to connect, check if the headset is paired with another gadget nearby. Many models automatically connect to the last known device, ignoring new requests until you manually break the old connection or reset the headphone settings.
Successful pairing is confirmed by a characteristic sound signal in the headphones and the appearance of the “Connected” status in the smartphone menu. From this point on, the audio stream, including system sounds and media files, can switch to the headset by default. It is important to understand that the profile HFP (Hands-Free Profile), which is responsible for telephone conversations, is activated automatically, but in rare cases requires manual checking in the advanced Bluetooth settings.
☑️ Check before the first call
Setting audio priorities and communication profiles
After a successful connection, a situation often arises when music is playing through the headphones, and a call suddenly comes through the phone speaker. This is due to the separation of data transmission profiles: A2DP for media and HFP/HSP for voice. In the Android operating system, each connected device has its own individual settings for use, which can be flexibly configured.
To make sure that calls will be sent to the headset, go to the Bluetooth menu, find the connected device and click on the gear icon or arrow next to its name. In the menu that opens, you will see switches for different types of traffic. Make sure that "Multimedia" and, critically, "Phone Calls" or "Call Sound" are activated.
- 📱 Phone calls: The main switch that directs incoming and outgoing voice traffic to the headset.
- 🎵 Multimedia: is responsible for playing music, video and sounds from applications.
- 🔊 Alarm sound: an optional parameter that allows you to hear alarm signals through headphones, if they are worn.
In some shells, for example in MIUI or One UI, the “Automatic Reply” function is available. It allows you to receive calls automatically after a certain time after the beep, which is especially convenient when driving a car. You can find this option in the accessibility settings section or in the menu of the “Dialer” itself under the “Auto answer” item. Activating this feature requires care so as not to start a conversation at the wrong moment.
If the sound from the headphones is quiet or intermittent after connecting, try turning off the “Absolute Volume” option in the Bluetooth settings, if available. This controls the volume of the system and headset separately, often solving the problem of low sound.
Call control: gestures, buttons and voice
The call control interface directly depends on the type of headset you have: completely wireless models (TWS) with touch controls or classic neck-mounted and full-size models with physical buttons. In the case of physical buttons, the logic is simple: one press - answer or end, hold - hang up or activate the assistant. Touch control requires more precise actions and getting used to.
Standard gestures for most TWS headphones are as follows: double-tapping the right earbud usually answers the call, and triple-tapping can activate the voice assistant. However, these actions are not set in stone and are often subject to reconfiguration through proprietary applications of manufacturers, such as Galaxy Wearable, Xiaomi Earbuds or Soundcore.
| Action | Physical buttons | Touch control (standard) |
|---|---|---|
| Reply to call | 1 short press | 2 taps |
| End call | 1 short press | 2 taps |
| Reject call | Hold (2-3 sec) | Hold (1-2 sec) |
| Voice assistant | Double tap | 3 taps |
Don't forget about the voice assistant management that is becoming increasingly intelligent. By saying an activation phrase like “Hey Google” or “Hey Siri” (on iPhone, but also works on Android via the Google Assistant), you can answer an incoming call with an “Answer” or “Reject” command without touching the headphones at all. This is the most hygienic and safe way to control on the move.
Use of third-party applications and automation
Standard Android tools are often sufficient for basic tasks, but enthusiasts may want to expand the functionality. There are specialized applications that allow you to create complex automation scenarios. For example, using the application MacroDroid or Tasker you can set the volume to automatically turn on when you connect a Bluetooth headset or send an SMS message when you reject a call with a button on the headphones.
Applications for volume control deserve special attention, since standard Android restrictions sometimes make it difficult to hear the interlocutor in a noisy environment. Equalizer applications and sound amplifiers, such as Volume Control or Precise Volume, allow you to fine-tune the frequencies specifically for voice communication, highlighting the mid-frequencies where human speech lies.
⚠️ Attention: Installing applications with deep system access to control audio requires caution. Some of them may conflict with system energy saving settings, which will lead to rapid battery drain or unstable operation of the Bluetooth module.
It is also worth mentioning applications from headphone manufacturers. Even if you lost the original application, many functions, such as firmware updates, are only available through it. Regularly updating the headphone software through the app often corrects bugs with sound desynchronization and improves noise reduction during a call.
Secrets of equalizer applications
Many users do not know that in the equalizer settings you can create a separate profile specifically for calls. Select the “Voice” or “Speech” preset, raise the sliders in the 1kHz – 3kHz range and lower the bass frequencies below 200Hz. This will make the other person's voice more intelligible even with a poor signal.
Solving common problems with sound and connection
Despite the reliability of the technology, users may encounter problems. One of the most common is echoes during a conversation. This occurs when sound from the headphone speakers enters the microphone and is returned to the other party. In most cases, lowering the volume or using models with high-quality noise reduction helps. If the echo persists, try switching the microphone mode in the Bluetooth settings, if such an option is available.
Another common problem is the low volume of the other person's voice. Check to see if the Pocket or Mute All Sounds mode is turned on, which can be activated by an accidental touch. It is also worth clearing the Bluetooth services cache. To do this, go to Settings → Applications → Show system → Bluetooth → Storage → Clear cache. This will not delete your pairings, but will update the service data.
- 🔌 Reset pairing: remove the device from the Bluetooth list and re-pair.
- 🔄 Reboot: Turning off and turning on the smartphone often solves problems with drivers.
- 🔋 Charge: low battery power of the headphones can lead to a decrease in transmitter power and deterioration in communication quality.
If the sound is interrupted or has a metallic tint, there may be interference from other wireless devices (Wi-Fi routers, microwave ovens). Try changing the location or switching the Wi-Fi router frequency from 2.4 GHz to 5 GHz, since Bluetooth operates in the 2.4 GHz range and may conflict with a busy channel.
90% of sound problems are solved by completely resoldering the connection (remove the device -> reboot the phone -> reconnect) or updating the headphone firmware through a proprietary application.
Features of working with different versions of Android
The control interface for Bluetooth devices can vary significantly depending on the version of the operating system and the manufacturer's skin. In “pure” Android (used in Google Pixel, Motorola, Nokia smartphones), the settings are concise and are located in the standard menu. At the same time, shells from Samsung, Xiaomi or Huawei can hide important switches deeper or add their own functions, such as “Game Mode” or “Sound Enhancement.”
For example, in Android 13 and newer, it became possible to see the battery charge of the headphones directly in the “Quick Settings” widget or in the multimedia card, which was previously only available through third-party widgets. Owners of older versions, such as Android 9 or 10, may need to install widgets from the manufacturer for similar functionality.
⚠️ Attention: Settings interfaces and menu item names may change with operating system updates. If you do not find the described item, use the search in your phone settings by entering “Bluetooth” or the name of your headphone model.
It is also worth considering that new high-quality codecs, such as aptX Adaptive or LDACmay not be supported old versions of Android or budget smartphone models. In this case, the audio will be transmitted in the basic SBC codec, which is fine for calls, but may disappoint audiophiles when listening to music. You can check supported codecs in the “For Developers” menu, finding the “Bluetooth Audio Codec” item.
Frequently asked questions (FAQ)
Why are the headphones connected, but the sound comes through the phone speaker?
Most likely, the “Telephone” profile is not activated in the Bluetooth settings for this device challenges." Go to Bluetooth settings, click on the gear next to the device and make sure the Call Sound switch is turned on. Also check if a different audio source is selected in the Phone application itself during a call.
Can I answer calls if the headphones are in the case?
It depends on the model. Some advanced models, such as Samsung Galaxy Buds Pro or Huawei FreeBuds, have an “Answer in ear” function that will not allow you to answer if the earphone is not in your ear. However, most models allow you to answer by pressing the case (if it supports touch controls) or will automatically transfer the conversation to the phone speaker if you did not remove the headphones within a few beeps.
How to make the call volume in the headphones higher?
Try increasing the volume with the buttons on the headphone body itself, and not on the phone. Sometimes volume levels are out of sync. You can also try turning off “Absolute Volume” in the “Developer Options” settings, which will allow you to adjust the volume independently. As a last resort, use sound amplifier applications.
Can the other person hear me if I speak through headphones with one microphone?
Modern TWS headphones use beamforming and noise reduction algorithms, using the microphones of both headphones even for voice transmission, to cut off background noise. Call quality is usually comparable to or better than a phone speaker because the microphone is closer to your mouth. However, in very windy weather, quality may suffer.
